HENRY L. DEVER, OF OVI'ENSBORO, KENTUCKY, ASSIGNORTO OWENSBORO DITCHER & GRADER COLIPANY, OF OWENSBOEO, KENTUCKY, A CORPORATION OF KENTUCKY.

ROAD GRADER AND DITCHER.

7 Application filed September 21, 1916. Serial No. 121,460.

T all whom it may concern Be it known that I, HENRYL. DEVER, a

citizen of the United States, residing at Owensboro in county of Daviess and State of Kentucky, have invented certain new and useful Improvements in Road Graders and Ditchers, oflwhi ch the following is a specification.

, My invention relates to an improvement in road-graders and ditchers.

The object is to provide a machine. of the character specified, which-is simple in construction and component parts, which is easily operated and controlled by the operator, and which provides safeguards for his protection in riding upon and manipulating the machine. This invention consists in a runner-beam, and an adjustably connected cutting or scraper-blade, together with anchor-blades for assisting in keeping the machine in line, in connection with various other partswhich go to makeup the complete machine, and which will be more fully described in detail'and pointed out in the claims. i

In the accompanying drawings Figure 1 is a plan View; and

Figure 2 is a side elevation.

The numeral 1 represents the cuttingblade, which is preferably made of plate metal plow steel with the upper and lower edges 2, 2, flanged or projected slightly forward to produce a scraping effect, these edges being sharpened so as to cut into the ground when being dragged over the same, the concavity thus formed in the blade causing the earth to roll outward and away from the machine, as from the mold-board of a plow. v

The numeral 3 represents the runner-beam which extends longitudinally throughout the length of the machine corresponding in' position to the typical land-side of an ordinary'plow.

A Y-shape-d brace 4 extends from the cutting blade to the runner-beam, forming a connection therebetween, and holding them rigidly at agiven distance apart, thus forming a main brace for the machine, and also serving as a means by which the angle of the machine may be varied as will now be explained. The forward end of the brace 4 terminates in pintles 5, 5, which extend 14, 14, which are connectedto the running-- beam by means of the rivets 15.

At the forward end of the running-beam, a nose 16 is riveted, and this is provided with an eye, which receives the bolt 18 for pivotally connecting the draft-bar 19 to the grader and scraper. This bar 19, is provided with several holes for the attachment of the draft chain 21, which is preferably connected thereto by means, of a swivel 20, and which has the hook 22 for the attachment of the team.

A main pulling beam 23, preferably of goose-neck shape, as shown in Figure 2, is connected at its forward end to the bar 19, and its rear end 2 f is rounded, and has an opening therein, andv the, forward end of the vertically-disposed hand-rail 25 passes through this opening in the rear end of the pulling-beam 28, as well as through a hole in the angle-iron 27 to hold the rear end of the pulling-beam 23 in position and attached to the cutting-blade, as shown in Figure 1, while the rear end of the hand-rail passes through the loop frame 26. t

An upright post 28 is 'removably secured in a socket 29, which is riveted to the scraper-blade, this post being used as a hand-rest or support for the operator when throwing his weight to the front of the machine.

An extension-member 31 at the rear of the blade is held in place by the. loop frame 26, and is preferably straddled by the forward end of the Y-shaped brace 4, while the rear end of the extension 31 passing through the loop-frame 26 is fastened by theqrear end of the hand-rail 25, which extends down through a hole in this extension. A blade 32 is held on the rear end of this A' rolling coulter 36 is revolubly supported at the forward end of the running beam by a journal-bolt 37, as shown in 8 Figures 1 and 2.

A seat 38 is mounted upon the upper end of a support 89, the lower end of which is fitted into the space between the T-shaped angle-iron l1 and a similar plate 40,.which two are connected together by angle-irons 41, which are secured thereto by bolts 12, thereby forming a platform for the operator to walk upon. A frame 43 is riveted to the upper end of the seat-support 39 by rivets or similar means 44, and a similar frame 45 is connected to the seat 38 by a bolt 46, a bolt 47 passing through both of these frames 43 and 45, and having a thumbnut 48 thereon. By releasing said thumbnut 48, the seat 38 may be adjusted to any angle, and by tightening same the seat is held securely at that angle.

In reversing the machine, the hand-rail 25 is removed; this releases extension-beam 31 and the pulling-beam 23, which may then be lifted out of the angle-iron socket 27. The upright post 28 is now lifted out of its socket, and, after the cutter-blade is reversed, these parts may then be returned to their relative positions.

In this way, a machine of few and simple parts is provided, easy and convenient to adjust and reverse without the requirement of more than ordinary skill.

More or less slight changes might be resorted to without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact construction herein set forth.

I claim:

1. The'combination of a running-beam, cutting-blade, pulling-beam. and a hand-rail removably connected with the cutting-blade, and affording a means of detachably securing the pulling-beam to the cutting-blade.

2. In a road-grader and scraper, a cutting-blade having an extension-beam, a pulling-beam detachably connected to the cutting-blade, and a hand-rail removably connected with the cutting blade for removably securing the pulling-beam and extensionbeam thereto.

3. A road-grader comprising in the main a cutting-blade and running-beam adapted to travel directly upon the surface to be graded or ditched, and a hand-rail connected with the cutting-blade, and adapted throwing his weight to that side of the machine.

at. The combination of a running beam, a cutting-blade, a draft-bar, a pulling-beam extending from the draft-bar to the cuttingblade, an extension removably secured to the rear end of the cutting-blade, and a handrail for detachably securin the extension beam and pulling-beam to the blade.

5. A road-grader comprising in the main a cutting-blade and running-beam adapted to travel directly upon the surface to be graded or ditched, and a hand-rail detachably connected with the cutting-blade, and adapted to serve as a support for the operator when throwing his weight to that side of the machine.

6. A road-grader comprising in the main a cutting-blade and a running-beam connected together, one of said parts having a platform, and the other having a post and hand-rail removably secured to and adapted to serve as hand-rests or supports for the operator when throwing his weight to that side of the machine.

7. A road-grader comprising a cuttingblade, a running-beam, a draft-bar, and a rigid goose-neck pulling beam connected with the draft-bar and extending around the edge of the cutting-blade entirely clear of the latter, and thence bent forwardly and connected at its end to the back of the cutting-blade.

8. In a road-grader, a reversible cutting blade having means on its back for detachably connecting a post, a hand-rail and a pulling-beam.

9. A road grader including a running beam, a reversible cutting blade, means for pivotally and adjustably connecting the two together at one end, draft means, and a rigid pulling beam of goose neck form connected at one end to the draft means, one end extending over and entirely clearing the upper edge of'the cutting blade, and connected to the blade at some point on the rear surface thereof.

10. A road-grader comprising a running beam, a reversible cutting-blade connected therewith and having on its back a loop frame, a socket, and integral iron brackets, and a post and hand-rail detachably connected with said socket, loop frame and brackets in either direction, whereby the post and hand-rail are adapted to project above the blade for the operator to. grasp, whether the blade be on the one side or the other of the running-beam.

11. The combination of a running beam, a reversible cutting blade pivotally connected thereto, a hitch-bar pivoted approximately at the point of juncture of the ruin ning beam and blade, and a rigid arched connection extending from the hitch -bar to serve as a support for the operator when around and clear of one edge of the connecting blade, to a point approximately at the transverse center of the back of the reversible cutting blade. p

12. The combination of a running beam,

- a reversible cutting blade pivotally connected thereto, a hitch-bar pivoted approximately at the point of juncture of the running beam and blade, and a rigid goose necked connection extending from the hitchbar around and clear of the upper edge of 10 the cutting blade and attached to the latter at a point approximately at the transverse center thereof.

Intestimony whereof I afliX my signature.
